I had made a request for this, actually, and it seems like it was already in BC, according to these Posters, here: https://us.forums.blizzard.com/en/wow/t/somechanges-huh/877410
Why? The Player interaction is still there.
The LFG Tool should NOT be confused with LFD. To help put your mind at ease, lemme give you a Video Link (it’s about fixing Drums, but there’s actually more, in that video, and it actually mentions LFD): https://www.wowhead.com/news=321063/leatherworking-drums-benefits-likely-changed-in-burning-crusade-classic
IDK about you, but it doesn’t sound like they’re going to be making the LFG system into LFD but just making it more “modernized” instead of how it was. It isn’t going to be some LFD, though.
